The front inner shell 11 and the rear inner shell 21 are each provided with a plurality of spaced-apart light-transmitting covers 4, each light-transmitting cover corresponding to a surface light source 3. The light emitted by the surface light source 3 shines into the cap through the light-transmitting covers 4, so that the emitted red light acts on the user's head, achieving a hair growth treatment effect.

[0053] The surface light source 3 is electrically connected to the matching external power control box 5, so that the surface light source assembly is powered by the external power control box 5. For example, Figure 8 As shown, the external power control box 5 includes a box body 51 and a control display panel 52 covering the box body 51. The control display panel 52 is equipped with control buttons and a micro display screen.

When the hair growth cap is worn by different users with different head shapes, the angle of the front inner shell 11 or the rear outer shell 22 can be adjusted according to the head shape, thus adapting to users with different head shapes and improving the flexibility and convenience of use. Moreover, by adjusting the angle of the front inner shell 11 or the rear outer shell 22, the angle of light irradiation can be changed to ensure that the light can accurately and evenly irradiate every part of the scalp, improving the hair growth effect.
